GAS-MIXING GASKET FOR INTERNAL-COMBUSTION ENGINES;

Application filed April 17, 1925. Serial No. 23,911.

My present invention has reference to a compressible gasket to be usedbetween the carbureter and the intake manifold of an internal combustion engine.

My object is the provision of a gasket for this purpose provided with spaced screens of finewire mesh, against which the fuel from the carbureter is forced to contact, and whereby the fuel will be broken to more effectively vaporize the same to insure a more perfect combustion thereof.

A further object is the provision of a comprcssible gasket for this purpose having spaced screens in the nature of bafiie members against which the fuel delivered from the carbureter forcibly contacts for more effectively mixing the fuel before its delivery to the engine cylinders, and wherein means is provided for supplying air to the gaseous mixture for insuring a thorough vaporization of the fuel to increase its combustible qualities and thereby materially reduce the fuel consumption without decreasing the power developed by the engine.

A still further object is the provision of a gas mixing gasket having means for admitting air thereinto for more effectively vaporizing the fuel delivered from the carbureter into the intake manifold, and wherein such air adn'iitting means also provides a drain for any condensation that may occur in the intake manifold.

A still further object is the provision of a gasket for this purpose characterized by simplicity of construction, cheapness in manufacture, and thorough efficiency for the purpose intended.

lVith the above recited objects in view the improvement resides in the construction, combination and operative association of parts. such as is disclosed by the following description, illustrated by the accompanying drawings, and pointed out with particularity in the appended claim.

In the drawings:

Figure 1 is a sectional view through the outlet end of a carbureter and the intake end of an intake manifold for an internal combustion engine, illustrating the application of my improvement therebetween, the latter being in section.

Figure 2 is a side elevation of the improvement.

Figure 3 is an enlarged sectional view on the line 3+3 of Figure 2.

Figure 4 is a sectional view on the line 44 of Figure 8.

In F igure 1 of the drawings, the numeral 1 designates the outlet or delivery end of a carburetor, and 2 the intake end of an intake manifold for an internal combustion engine. As is well known the confronting ends of the carbureter and manifold are flanged outwardly, and to establish a tight joint between these elements a compressible gasket is employed. My improvement is designed to take the place of the ordinary gasket, and it will be apparent, as the description progresses that my said improvement may be constructed at little more expense than that of the ordinary gasket.

The improvement is broadly indicated by the numeral 3 and has its sides in the nature of thin copper plates 4. The plates are provided with the usual central openings and also with the usual bolt receiving openings. Between the plates 4 I arrange an asbestos or like compressible body 5. The body is, of course, formed with a central opening and with bolt openings to align with the openings in the plates 4. The body 5 has its sides formed with depressions 6 that surround its said central opening 7 and there is pocketed in each of these depressions a screen member 8. The mesh of the screens 8 is comparatively line, and preferably the strands of one of the screens is arranged in-' termediate of the strands of the adjacent screen. The screens are pocketed in the depressions 6 by the thin copper plates 4, and any desired means, preferably, however in the nature of adhesive, is employed for holding the plates and body united.

Vith a construction as above described it will be apparent that the fuel from the carbureter will forcibly contact with the spaced screens 8, the said screens serving as baffle members for breaking up the particles of fuel and render the same in a better condition for combustion.

The body 5 has a central opening therethrough, and I pass through this opening the ends of a tube 9. The tube is in the nature of a roll of very fine wire mesh and as the same communicates with the atmosphere and is arranged between the spaced screens 8 outside air will be admitted to the gaskets and caused to miX with the explosive charge as it passes between the screens 8 whereby any particles of fuel in the explosive charge will be more effectively vaporized, the result being that a homogeneous mixture is delivered to the engine and amore perfect combustion is obtained. lhe reticulated tube not only serves for the admission of air to the gasket, but permits of any moisture from condensation in the manitold passing through the lower portion of the inner screen or baflle member 8. and through the lower portion of the said tube onto the ground.

The simplicity of my constructioin the clieapness of its manufacture and marketing, and its manifest advantages will, it is thought be perfectly apparent from the foregoing so that further detailed description will not be required. Of course, such slight changes as fall within the scope of my claim may he resorted to.

Having described claim A mixing device in the form of a gasket including thin copper side plates, a compressible body between said plates having a central opening with depressions in its sides surrounding the central opening, screens seated in said depressions and having their peripheral edges covered by the side plates, and a tube of fine wire mesh passing centrally through the body, between the screens and having its ends communicating with the atmosphere.

In testimony whereof I affix my signature.

the in vention, I

CHARLES M. TANSILL.
